[Chameleon] current, actual legend

[Paul Spencer]

Markus,

you are correct, layer_visible is only available in mapscript 4.3/4.4

if I understand the problem correctly, you are saying that when you use 
opt_flags=0 then layers get turned off?

If this is the case, with beta 3 you can add the following attribute to 
the LegendTemplate widget tag:

CONTROLVISIBILITY="false"

Theoretically, in an earlier version, it should have worked if you had a 
legend template that did not include checkboxes - so your template 
should have worked - but for some reason I could never figure out the 
logic to do this correctly without checkboxes.  So the fix was to 
introduce CONTROLVISIBILITY :)

Cheers,

Paul
